Communal coping has been linked to better psychological and physical health across a variety of stressful contexts. However, there has been no experimental work causally linking communal coping to relationship and health outcomes. In addition, research has emphasized the collaboration over the shared appraisal component of communal coping. The present study sought to isolate the role of appraisal by manipulating whether dyads viewed a stressor as shared or individual. Friend dyads (n = 64 dyads; 128 participants) were randomly assigned to view a stressor as either a shared or an individual problem, but both groups were allowed to work together. Across self-report and observational measures dyads reported more collaboration and support, better relationship outcomes, and more positive mood after the stressor in the shared than the individual appraisal group. This is the first laboratory evidence to establish causal links of communal coping—specifically shared appraisal—to positive relationship and health outcomes.

Syntactic Derivation

Function words are commonly considered to be a small and closed class of words in which each element is associated with a specific and fixed logical meaning. Unfortunately, this is not always true as witnessed by negation: on the one hand, negation does reverse the truth-value conditions of a proposition, and the other hand, it does not, realizing what is called Expletive Negation. This chapter aims to investigate whether a word that is established on the basis of its function can be ambiguous by discussing the role of the syntactic derivation in some instances of so-called Expletive Negation clauses, a case in which negation seems to lose its capacity to deny the proposition associated with its sentence. Both a theoretical and an experimental approach has been adopted.

✓ The role of focal ischemia and the altered circulation in a brain scar in relation to focal cerebral seizures has provided one of the continuing problems in the experimental approach to the mechanism of epilepsy. The brain of the epileptic patient as observed during craniotomy appears to show more vasomotor lability than the normal brain. This lability seems uninfluenced by sympathectomy or carotid artery sinus denervation. Epileptic lesions of all types show cytological evidence of ischemia. It seems likely that some undiscovered secret of cerebral circulation is the ultimate cause of epilepsy.
